Information System (IS) is a collection comprised of people and computers that interprets information.
Information Systems is a large umbrella referring to systems designed to create, store, manipulate, or disseminate information. An example of an information system is a pencil and a piece of paper. The two objects themselves are just tools, but together they create a system for writing (information).Information technology falls under the information systems umbrella but has nothing to do with systems per say. IT deals with the technology involved in the systems themselves, e.g. an information system like wiki.answers.com contains many information technologies. Servers, server operating systems, web server software (IIS, Apache, et al.), and code written for the web server software (PHP, C#, VB, PERL, Ruby, et al.).
Strategic level information systems are designed to support strategic decision-making by top-level management. They focus on long-term goals and objectives of the organization and help in aligning information technology with overall business strategy. These systems typically include executive support systems and business intelligence tools to provide insights for strategic planning and resource allocation.
The field of study that focuses on both behavioral and technological understanding of information systems is typically referred to as Information Systems (IS) or Management Information Systems (MIS). This field combines knowledge of technology with an understanding of how people and organizations interact with and use information systems to achieve their goals.
Information technology (IT) refers to the use of computing technology to manage and process information. It encompasses hardware, software, networks, and data storage systems that enable organizations and individuals to create, store, access, and exchange information.
